Said outer or receivingend portions of the clipsf9 are disposed at an angle away from the plate 7 thereby facilitating the proper and ready engagement therewith of the inner longitudinal edge portions' of curved side plates 10. The curved. side plates 10 are each of a length substantially co-exten'sive in length with the base plate 7 and possess sulficient inherent resiliency to allow themselves to be transversely flexed to conform to the interior curvatures of arcuate clamping members '11 secured therearound.

The curved base plate 7 is also adaptedto transversely flex somewhat to accommodate itself to the clamping members-l1 and the inherent resiliency or flexibility of the lates I 7' and ,lO permitslsaid plates to, be emp oyed in thejproduction of piling or kindredlcolumns of v'aryin diameters as determined by the size of the c amping members 11 employ ed' in connection therewith. 'Ihe curved side plates 10 are of such transversedimene 1 sions to assure thevupper marginal edges thereof beingspaced apart in the mold assembly to provide anupper opening 12 ex- '-'tending longitudinally of the mold thereby providing for effective pouring of the cementitious material into the mold assembly and also'r permittingsuc'h tarnping as may be required I The clamping members ll las h'erein disclosed are arranged in-pairs with the membersl'l of each pair pivotally' connected; as

Said end portion of the lever is pivotally] connected with the free end portion of the other clampingmember 11, as at 17 5 so that'upon' proper pivotal 'movernents'of said lever, with the loop 15 engaged with the hook 14,the pair off-clamping members'll may be broughtinto proper holding arrangementaround the mold asembly. The clamping members ll-ar'e disposed with respect to the-horizontal mold assembly-so that the pivotal connections: 13 are'onl one I :side of the moldcoincident with the horizon- "talplaneoftheaxis of'the mold; while the loops and levers are directly opposite on the I I otherlside'of the mold.
